Just 24 hours on from Kew Gardens winning the English St Leger at Doncaster, jockey Ryan Moore employed different tactics aboard Flag Of Honour, who was sent off the 2-1 favourite in the six-runner field.

His opponents did include the Irish Derby winner Latrobe, though, and the two had it between them from some way out.

Having won the Curragh Cup and the Leger Trial on his last two starts, showing a liking for this course and distance, Moore knew there were no stamina doubts and kicked on some way from home.

Latrobe kept him honest inside the final two furlongs, but his petrol tank began to ebb inside the final 100 yards and Flag Of Honour took his record to five wins from 10 starts in winning by two and three-quarter lengths.

O’Brien said: “He’s a tough, hardy horse who handles an ease in the ground and he stays very well.

“He has enough class for a mile and a half, but he gets this extended trip well. He’s progressing all the time and is really going the right way and Ryan felt he quickened well.

“The way he picked up there you wouldn’t say that he’d have to step to extreme trips. He’s after having a busy time so we’ll have to see whether he runs again this year.

“He has an entry in the Melbourne Cup, but I’ll have to talk to the lads and see what they’d like to do.”

O’Brien added: “This was always the plan. With Kew Gardens, the better the ground the better he’d like it. This horse will handle an ease and even if it got soft it wouldn’t bother him.

“When Order Of St George went off to stud this horse was always going to come here to split them up.

“I asked Ryan about Kew Gardens yesterday and he thought he doesn’t have to go Cup trips and this horse is probably the same.

“Order Of St George was a very unique horse. He was able to be competitive in Arcs and races like that and still able to get the Cup trip.”

“When you go beyond two miles you’re never sure what’s going to happen. This horse looks like he could get up to it, but whether he gets beyond it and further – he mightn’t need to.

“He picked up today like a horse that doesn’t need to go extreme distances. You’d imagine he could go forward but he doesn’t have to.”

Moore said: “He’s a very good horse, he’s grown up an awful lot and is taking his racing very well.

“He’s got a fantastic attitude and it was very comfortable the whole way.

“That’s three he’s won over a mile and six now, so obviously he likes it, but he was a good two-year-old and I think we’ve found the key to him now.”

The Irish St. Leger was established in 1915, and it was originally restricted to three-year-olds. The first horse to win both the English and Irish St. Legers was Royal Lancer in 1922.

The first Irish St. Leger winner to complete a Triple Crown (having previously won the Irish 2,000 Guineas and the Irish Derby) was Museum in 1935. The only subsequent horse to win all three races was Windsor Slipper in 1942.

The Irish St. Leger became an open-age race in 1983, and there have been several repeat winners since then. The most successful has been Vinnie Roe, with four consecutive victories from 2001 to 2004.

The leading horses from the Irish St. Leger sometimes go on to compete in the Melbourne Cup.
